(Phys.org) —Mother Nature's helper in turning nitrogen from the air into ammonia is an enzyme called nitrogenase that uses molybdenum and iron; scientists want to learn natural catalyst's secrets and apply ...

(Phys.org) —Researchers at Eindhoven University of Technology in The Netherlands have found that treating pavement with titanium oxide causes a reduction in nitrogen oxide air pollution. In their paper published in the ...

It's nearly 50 years since Gordon Moore predicted that the density of transistors on an integrated circuit would double every two years. "Moore's Law" has turned out to be a self-fulfilling prophecy that ...

For the first time, researchers have successfully demonstrated an interaction between ocean currents and bacteria: The unexpected interaction leads to the production of vast amounts of nitrogen gas in the ...

(Phys.org) —This new image, snapped by NASA/ESA Hubble Space Telescope, shows the star HD 184738, also known as Campbell's hydrogen star. It is surrounded by plumes of reddish gas—the fiery red and orange ...

A new study shows that the reduction of pollution emissions from power plants in the mid-Atlantic is making an impact on the quality of the water that ends up in the Chesapeake Bay. The study by scientists ...

Human-induced changes to Earth's carbon cycle - for example, rising atmospheric carbon dioxide and ocean acidification - have been observed for decades. However, a study published this week in Science showed ...

(Phys.org) —A study conducted by Alberto Salvo and Franz Geiger of the National University of Singapore and Northwestern University respectively, has revealed that when drivers switch from using ethanol ...

By combining projections of climate change, emissions reductions and changes in land use across the USA, an international research team estimate that by 2050, cumulative exposure to ozone during the summer will be high enough ...

Quantum computers are experimental devices that promise exponential speedups on some computational problems. Where a bit in a classical computer can represent either a 0 or a 1, a quantum bit, or qubit, can ...

A simple, low-cost and eco-friendly method of creating nitrogen-doped graphene nanoplatelets (NGnPs), which could be used in dye-sensitized solar cells and fuel cells, is published in Scientific Reports today. ...
